.... The resultant of the horizontal components characterizes the irregularity of the chip flow state. The chip flow direction is also analyzed in a cutting force model, in which the chip flow angle is determined at the minimum cutting energy. In the model, the change in the chip flow angles is simulated...

.... In this paper, we examine the hypothesis of the cause of Yotari. First, we formulate the yarn based on physical constraints. Next, we formulate the contact and friction between the yarn and the knitting parts. Finally, we dynamically simulate the behavior of the yarn as it is woven by the knitting parts...

..., it is difficult to obtain the optimal solution to such scheduling problems in a practical time. For this scheduling problem, we propose a new solution algorithm combining scatter search with path relinking and operation simulation. In this paper, we describe previous research, our target process, the new solution...
